如何在Listview绑定Xamarin.Forms内创建网格 [英] How To Create a Grid inside a Listview Binding Xamarin.Forms

问题描述

如何在具有数据绑定的ListView中创建网格?我正在使用Xamarin.Forms创建此应用.

How can I create a Grid inside a ListView with data binding? I am creating this app with Xamarin.Forms.

如果我不知道需要多少行和列，该如何在ListView绑定内动态创建Grid?

If I don't know how many rows and columns I need, how can I dynamically create the Grid inside the ListView binding?

这是我到目前为止所拥有的:

This is what I have so far:

<ListView x:Name="List" HasUnevenRows="True">
  <ListView.ItemTemplate>
   <DataTemplate>
    <ViewCell>
      <ViewCell.View>
        <Grid Padding="10,10,10,10">
          <Grid.RowDefinitions>
            <RowDefinition Height="200"></RowDefinition>
          </Grid.RowDefinitions>
          <Grid.ColumnDefinitions>
            <ColumnDefinition  Width="200"></ColumnDefinition>
          </Grid.ColumnDefinitions>
          <StackLayout BackgroundColor="#313FA0" Grid.Row="0" Grid.Column="0" HeightRequest="200" WidthRequest="200">
            <Label Text="{Binding NUMBER}" FontSize="50" TextColor="White" HorizontalOptions="CenterAndExpand" VerticalOptions="CenterAndExpand"/>
            <Label Text="{Binding NAME}" FontSize="30" TextColor="White" HorizontalOptions="CenterAndExpand" VerticalOptions="CenterAndExpand"/>
          </StackLayout>
        </Grid>
      </ViewCell.View>
    </ViewCell>
   </DataTemplate>
  </ListView.ItemTemplate>
</ListView>

在此代码中，仅创建一行和一列.如果我有多个数据点，如何解决此问题?例如，如果我需要一行包含两列.

In this code only one row and one column are created. If I have multiple data points, how can I resolve this issue? For example, if I need one row with two columns.

提前谢谢.

推荐答案

您也可以使用下一个方法示例(通过xaml，正面).

You can use the next approach-example (throug xaml, front side) as well.

<ContentPage.Resources>
      <ResourceDictionary>
        <Color x:FactoryMethod="FromHex" x:Key="fondoBlancoPalido">
          <x:Arguments>
            <x:String>#F2F2F2</x:String>
          </x:Arguments>
        </Color>
      </ResourceDictionary>
    </ContentPage.Resources>

<ListView x:Name="listView" HasUnevenRows="True"  ItemsSource="{Binding .}" BackgroundColor="{StaticResource fondoBlancoPalido}">
        <ListView.ItemTemplate>
          <DataTemplate>
            <ViewCell>
              <ViewCell.View>
                <Grid Padding="5">
                  <Grid.RowDefinitions>
                    <RowDefinition Height="60"></RowDefinition>
                    <RowDefinition Height="60"></RowDefinition>
                    <RowDefinition Height="10"></RowDefinition>
                  </Grid.RowDefinitions>
                  <Grid.ColumnDefinitions>
                    <ColumnDefinition Width="1*"></ColumnDefinition>
                    <ColumnDefinition Width="2*"></ColumnDefinition>
                    <ColumnDefinition Width="3*"></ColumnDefinition>
                  </Grid.ColumnDefinitions>

                  <Button Grid.Row="0" Grid.Column="0" Clicked="OnStartClicked" Image="play.png" BackgroundColor="Transparent" HorizontalOptions="Center" Grid.RowSpan="2"/>
                  <Label Grid.Row="0" Grid.Column="1" Text="Hora de Inicio: " XAlign="Center" YAlign="Center" TextColor="Black" FontAttributes="Bold"/>
                  <Label Grid.Row="0" Grid.Column="2" Text="{ Binding attribute3 }" XAlign="Center" YAlign="Center" TextColor="Black"/>
                  <Label Grid.Row="1" Grid.Column="1" Text="Encargado de la Tarea: " XAlign="Center" YAlign="Center" TextColor="Black" FontAttributes="Bold"/>
                  <Label Grid.Row="1" Grid.Column="2" Text="{ Binding attribute4 }" XAlign="Center" YAlign="Center" TextColor="Black"/>
                  <BoxView Color="Navy" HeightRequest="2" Grid.Row="2" Grid.Column="0" Grid.ColumnSpan="3"/>
                </Grid>
              </ViewCell.View>
            </ViewCell>
          </DataTemplate>
        </ListView.ItemTemplate>
      </ListView>
